Asynchronous MirroringIn the diagram above, the two write requests have been written to the source volume and are in the queue tobe sent to the target system. However, control has already returned back to the application who initiated thewrites.In the diagram below, the third write request has been initiated while the first two writes have successfullybeen written to both the source and target volumes. While in the mirroring state, write requests are sent to thetarget volume in time order. Thus, the target volume is always an exact replica of the source volume at somepoint in time.DataKeeper for Windows Technical DocumentationPage 14
Mirror PAUSEDMirror PAUSEDIn the event of an interruption to the normal mirroring process as described above, the mirror changes from theMIRRORING state to a PAUSED state. All changes to the source volume are tracked in the persistentbitmap file only and nothing is sent to the target system.DataKeeper for Windows Technical DocumentationPage 15
